If I remember in Windows 2000, we used to grant Write permissions to end users on a Folder, example Fold1. This will give them the capability to create new folders and files under Fold1. This will prevent them to delete files and folders that have been created by other users. it will also prevent them from copying or moving a folder create by other users to different location.
I am not sure why in the newer files systems version, when I gave user write permissions to a folder, they could not create anything inside the folder.
Any help ?
